BOTTLE-FILLING MACHINE.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed April 23, 1906. Serial No. 313,146.

To all whom it may concern:

Be it known that I, CHARLES L. BASTIAN, a citizen of theUnited States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Bottle-Filling Machines, of which the followingis a specification.

This invention relates particularly to the filling valve mechanisms of machines for iilling beer or other carbonated liquids and its object is primarily to avoid foaming during the filling operation.

In the accompanying drawings Figure 1 illustrates a filling valve mechanism embodying my invention, Fig. 2 is a sectional view on the line 2-2 of Fig. 1. Fig. 3 is an en larged detail sectional view of the bushing.

Referring to the drawings 5 designates the body of the iilling valve mechanism and it is provided with a central bore 6 into which the iillinr tube 7 is secured. The body may bel secuised to the bottom of the tank or head of the filling machine (not shown) in any suitable manner and it is provided with a seat 8 at the upper end of the bore 6 to receive a liquid valve 9 which is carried by a cross piece 10. Rods 11 are slidably arranged in the body 5 and carry the cross piece. Springs 12 are held in lace on the rods below the body by adjustab .e nuts 13 or other suitable devices and the tension of the springs is exerted to normally hold the' liquid valve against its seat. A head 14 is slidably arranged on the filling tube and on the lower ends of the rods'll. This head is provided with a seat 15 on its lower face for the mouth ofthe bottle and it has an enlarged bore 16 which communicates by a lateral passage 17 with a chamber 1S. An air tube 19 is screwed into a nipple 2O which in turn is f screwed into the upper end of the chamber 18', and the upper end of this air tube projects through the body of the valve and carries an air valve 21 which has a seat 22 on said body. This air valve is inclosed within an elongated tubular housing 23 which'is secured in upright position to the body over the air valve and a spring 24 inclosed within this housing constantly bears on the air valve to assist the springs 12 in returning the movable parts to their normal position. An extension of the housing in the form of a tube 25 carries the air discharge' above the level of the liquid in the tank.

In Patent No. 768,962 dated Aug. 30, 1904 may be adapted.

provision is made for retarding the flow of air during the lling operation from the bottle to the tank or head of the filling machine in order to` compensate for the weight of the liquid in the filling tube, thereby to prevent the forcible discharge of the liquid into the bottle and avoid foaming. My present invention accomplishes this result in a different manner by restricting the iiow of liquid from the tank into the filling tube and then permitting an expansion in the filling tube to reduce the pressure and prevent the forcible discharge of the beer into the bottle. In the upper end of the filling tube a bushing 26 is secured in a suitable manner and this bushing has a tapered bore 27 with its largest di-v ameter at the lower end 28 of the bushing and its smallest diameter at the upper end 29 of the bushing where it connects with a cup or conicalshaped cavity 30. The upper end of the bushing is provided with this cup or conical shaped cavity to avoid an abrupt shoulder which would have a tendency to agitate the beer and produce foaming. This type of valve mechanism is employed in a iilling machine which comprises a lifting mechanism of suitable character for carrying the bottle or other receptacle up on the filling tube and against the head and then moving the bottle and head up together to first open the air valve 21 and permit an equalization of pressure in the bottle and in the tank or head of the filling machine until head engages the nuts 13 and lifts the rods 11 and cross piece 1() to unseat the liquid valve 9. The flow of beer from the tank into the filling tube is restricted by the tapered bore of the bushing and after the beer passes the smallest diameter of the bore it gradually expands during its passage through the remainder of the bore and as it enters the iilling tube below the bore, which reduces the pressure and prevents the forcible' discharge of the beer into the bottle. This compensates for the hydrostatic head of the beer in the filling tube, the pressure in the bottle and in the tank or head of the filling machine being equalized, and foaming in the bottle is entirely avoided.

The invention is not restricted to its application with a iilling valve mechanism of this specific type but it may be used in the valve mechanism of said Patent No. 768,962 and in other valve mechanisms to which it Whet I claim and desire to secure by Letters Patent is:-

In a llng machine, the Combination of a lhng tube having a. bore throughout its 5 length, e 'bushing in the upper end of the {111- ing tube, said bushing having a @up or conical shaped cavity at its upper end and also having a tapered bore With its smallest diameter at said cavity and its largest diameter at the lower end of said bushing.
